Cell membranes
Controls what goes in and out
2 of 26
Cytoplasm
Where chemical reactions can take place
3 of 26
Ribosomes
Where proteins are made in the cell
4 of 26
Vacuole
Contains cell sap
5 of 26
Chloroplasts
Where photosynthesis occurs, too make food for the plant. Contains a green substance called chlorophyll
6 of 26
Mitochondria
Where respiration occurs. Releases the energy needs for cell to work

Yeast cell
Microorganism,has a nucleus,cytoplasm and cell membrane surrounded by a cell wall.
8 of 26
Bacteria Cell
Single celled microorganism, a bacterial cell has cytoplasm and cell membrane surrounded by a cell wall. Has no nucleus instead genetic material floating in cytoplasm

Diffusion
The spreading out of particles from an area of HIGH CONCENTRATION to an area of LOW CONCENTRATION
10 of 26
The bigger the difference in concentration...
The faster the diffusion rate
11 of 26
Cell Membranes...
Only small molecules can diffuse through cell membranes e.g oxygen,water, amino acids and water. Big moleculesN

Egg cells are specialised for reproduction by...
is to carry female DNA and nourish embryo therefore contains huge food reserves. When sperm fuses with the egg, The egg's membrane instantly changes its structure by stopping any more sperm getting in , ensures offspring has correct amount of DNA

Sperm cells are specialised for reproduction by...
Carry male DNA to female DNA. Long tail and straemlined head to help it to swim. Lots of mitochondria to provide cell energy. Enzymes in the heads to digest through egg cell membrane

What is Differentiaton
The process off which cells become specialised allowing them to carry out a particular function

Glandular tissue
makes the digestive juices to digest the food in the stomach
20 of 26
Epithelial tissue
which covers the outside and inside of the stomach
21 of 26
Glands
e.g the pancreas and salivary glands - produces digestive juices
